Re: Beta packages within stable releases



How timely.

There's a couple of things going on here.  The important ones I think are
the first two of our mission statements:

https://fedoraproject.org/wiki/Overview#Our_Mission

"Always strives to lead, not follow."

"consistently seeks to create, improve, and spread free/libre code and
content."

What you are asking, in my opinion, is to slow down a bit.  This doesn't
necessarily have to conflict with our first mission but it might put it at
risk.  There's been much soul searching related to this very topic over
the last several weeks (I assume you've seen it).

I personally prefer to have Thunderbird 3 and Firefox 3.5.3 on my desktop
because I understand when things are and aren't working right and can
communicate that to upstream.  In my opinion if you require older versions
of these critically important software packages, there are other
distributions that offer it.  For example the most recent version of
Ubuntu ships the 3.0.X tree of Firefox.

Others disagree, putting a much higher value on market share and user
quantity.  In that instance, slowing down might make sense.  We would have
a more stable environment to work in, which is desirable by most.  We'd
also be less distinguishable from other distros.  Our recent additional
commitment to QA will help some of the stability issues many complain
about, I don't think there's any plan in place that would detect the
specific issues you are describing.

In my opinion both Firefox and Thunderbird benefit from us doing early
adoption of their software.  Additionally, the more stable versions of the
software packages you are looking to use are even more stable as a result
of Fedora getting them first and helping find and fix those bugs.  There's
a lot of talent here to do that sort of work.

As far as the bigger question of what 'stable' means.  All upstreams have
different opinions on what stable means.  Even if they didn't, our
packagers might disagree.  I know we have guidelines on how to package
pre-release software, I do not know if there are any policies or
guidelines around what is and is not acceptable to be in Fedora.
Generally if it's Free Software and it compiles, it can get in.  I'm not
even sure what body decides this though I'd assume some mixture of the
packaging committee and FESCo.

Looking outside the box a bit, there's also the option of shipping both
versions of some of these 'day to day' packages.  Providing both
additional stability for the people that want it, and a bit of blood for
those that can handle it.  Though this puts additional strain on the
packagers.
